05 A! A. LAw/as/vcE Patented Apr. 14, 1931 UNITED STATES OSCAR A LAWRENCE, OF SAN FRANCISCO, CALIFORNIA STOOL, CHAIR, AND TABLE CONSTRUCTION Application filed December 26, 1928. Serial No. 328,362.

This invention relates particularly to a construction of stools, chairs, tables and the like.

An object of the invention is to provide a stool, chairzor the like, formed of a single sheet or disc of metal suitably reinforced to resist torsional strains, and provided with a plurality of sockets at spaced points about the periphery thereof into which the ends 1 of supporting legs are adapted to be detachably engaged, whereby, for the purposes of shipment or storage, the apparatus can. be packed into a relatively small area, or when assembled, forms a rigid and sturdy structure having many varied uses.

A further object of the invention is to provide a portable stool which may be placed on the seat of a chair of average heighth to give greater height thereto, being especially useful to form a high-chair for children or adults, or in other instances where a higher than ordinary seat is desirable.

Other objects of the invention are to provide a portable and demountable stool, chair 5 or table that is superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general eficiency.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it maybe embodied.

In the accompanying one sheet of draw- Fig. 1 is a plan view of a fragmentary part of a device constructed in accordance with my invention.

Fig. 2 is a cross section taken through Fig. 1 on the line 22.

Fig. 3 is an enlarged plan view of the connection between the leg and table disc.

Fig. 4 is a section taken through Fig. 3 on the line 44. a

Fig. 5 is a plan section taken across one of the legs on the line 5-5 of Fig. 6;

Fig. 6 is a vertical section of the foot end of one of the legs.

In detail the construction illustrated in the drawings com rises a. sheet or disc of material 1, prefera ly a light gauge metal, which may either be circular, square, rectangular, or of any other contour desired. The entire edge of the disc is flanged or shouldered or rolled as at 2, whereby the edge 3 of the roll will lie on the inside. The face of the disc is provided with central and radial embossments or depressions 4 therein to stiffen and reinforce the said disc against torsional strains. The rolled edge of the disc is resilient or springy, for the purpose to be hereinafter described.

A plurality of sockets formed of pairs of depressions 5 and 6 are countersunk or impressed on the upper face of the dies in equidistant spaced relation around the perimeter thereof. The base of the depressions 5 and 6 lies below the plane of the upper face of the disc and one side of each depression, on the under side of the disc, is cut away as at 7, facing the inner side of the rolled edge. A pair of spaced prongs 8 and 9 are cut from the disc between the depressions 5 and 6 and the rolled edge.

A plurality of legs 10 are provided, each individual leg being complementary to one of the sockets. The legs 10 are all duplicates, one of the other, and each consists of a strip of metal of light gauge, bent into a channelor U shaped cross section. The ends of each three sided leg, at the bottom, are flanged outwardly as at 11, 12 and 18, to form a three. toed foot for said leg. The foot flanges of each leg are suitably covered with rubber 14-, or other material to prevent the same from marring or scratching any surface they may contact with.

The upper end of each leg is provided with side flanges 15 and 16 and an end flange 17. The side flanges 15 and 16 are equipped with extended ends 18 each of which are adapted to pass through the openings 7 into the respective pairs of depressions 5 and 6, and said flanges also have cuts 19, therein into which the prongs 8 and 9 pass. The end flange 17 on each leg is adapted to be sprung I rolled edge 2, the flanges 15 and 16 are tightto disc and the edge of the roll.

In order to mount the legs 10 on the disc 1, myhand at an the side flanges 15 and 16 on each leg are en- 14th day of De OSCAR A. LAWRENCE.

tered into the companion pair of sockets 5 and 6, the space between the under face of the disc and the upper face of the base of each depression being of such dimension as to hold the thicknessof the flanges 15 and 16 in snug engagement with the aforementioned surfaces. T e cut away edge of the base of each de ression also forms a fulcrum point about which each leg 10 may be swung when engaging the end flange 17 on each leg with the springy rolled edge 2. As said flan e 17 is forced into frictional engagement wit the lyinterlocked with the depressions 5 and 6 and each leg is thereby frictionally attached in detachable engagement with the under sideofthe disc. If desired, the prongs 8 and 9 may be bent over to lock the leg flanges in a set position on the disc.

- Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. In combination, a disc having a resilientflange around the edge thereof; and le s to engage the disc at spaced points aroun the perimeter thereof, each le having a projection thereon engageable w th a socket on the disc, and a argojection on the opposite side of each leg to sprung into frictional contact with the resilient flange to hold said leg in detachable engagement with the disc. N

2. A device of the character described comprising a disc having the edge thereof resiliently rolled to lie on one side of the disc and with the edge of the roll overlying the under side thereof; a plurality'of pairs of depressions formed on the upper face of the disc in spaced relation therearound, each pair of depressions having a side thereof open,

facing the rolled edge; and a lurality of .legs each having an end thereo detachably engaged in the open side of each pair of depressions and between the under side of the disc and the overlying rolled edge.

' 3. A device of the character described comprising a disc having the edge thereof resilviently rolled to lie on one side of the disc and with the edge of the'roll overlying the bottom face thereof; a plurality of pairs of depressions formed on the upper face ofthe disc in spaced relation'therearound, each pair of depressions having a side thereof open, facing the rolled edge;.and a plurality of legs each having the opposite ends thereof flanged, one flanged end of each leg forming a foot therefor and the opposite flanged edge of each leg abutting the bottom face of the disc and being detachabliy e open side of each pair of pressions and engaged in the In testimon past the resilient inner edge 3 of the roll 2 tween the said bottom face and the overlying whereof, I have hereunto set Franc1sco, California, this cember, 1928.
